Remember, I'm not necessarily an expert, but I can point out some errors...


Metallic Doom

Okay, good name.

shape: drillzilla low box

Don't you mean A low box shape like Drillzilla?

weight:150kg

Okay.

dimensions:43 x 38 x 7

According to my calculator, and the formula stating 2.5cm = 1in, the dimensions are 107cm x 95cm x 17cm, which are good.

colour: left hand side blood red, left hand side black

Don't you mean the right hand side is black? Anyways, okay.

Drive: 2 36v LEM-170 motors, powered by 10x 36v A123 Battlepacks, giving me an average of 26hp.

To quote Kody:

LEM-170s only turn well 1 way.
So you'd have to get the motors rewound to work well both ways. Also there are no such things as 36v A123s. The closest thing would be a 36.3v, so you'd need 11 packs.

Locomotion: 2 Drillzilla-style shuffling feet at the rear, giving Metallic Death good traction and pushing ability.

For some reason, I feel you directly copied Me Name is Death's Locomotion stat, aside from putting your own robot's name in...

speed: 40mph

Too fast. You want a speed of at max 20mph.

ground clearance: 0mm at the sides, 5mm front and back

Okay.

turning circle: 0m

Okay.

weapons: drillzilla steel jaws and a pneumatic, double headed version of mortis' axe, powered from a co2 divers bottle,
delivering 400kg
of of pressure per square centimeter

The weapon description is very vague, plus with more detailed Drillzilla jaws, you won't need the axe.

strenghs: bloody fast

A bit too fast, actually.

weakness: robot bounces in the air when axe strikes

You don't really describe how the axe strikes...

bio:my (i believe) 6th design thats is like and updated drillzilla

If you add an axe, that takes away the Drillzilla feel. Plus there's no srimech and no armour.
